Definitions

  • the invention relates to a burner arrangement, in particular for a gas burner, with a gas and an air supply line, both of which end in the area of a gas-air mixing chamber, with swirl-generating devices which create a vortex flow of the gas within the mixing chamber and in the downstream combustion zone Generate air mixture, at least a portion of the combustion air flowing laterally into the mixing chamber via channels which can be changed in cross-section and are embedded in the wall of the mixing chamber.
  • a so-called dual burner is shown in DE-OS2 729 321, in particular FIG. 12.
  • the known burner is primarily designed as an oil burner, it can also be operated with gas, the oil nozzle being bypassed with the aid of a channel which opens into the mixing chamber.
  • the gas supply is regulated by a rotatable perforated disc that gradually releases the channel by rotating the bore.
  • the air supply through channels opening laterally into the mixing chamber can be adjusted with the help of an actuator that changes the cross sections of the laterally opening channels to create a vortex.
  • Such a burner arrangement is also advantageously to be used, for example, to burn finely divided aerosols or dusts, which can be introduced either in a gas stream or in a compact form in the region of the strong combustion air flow.
  • the fuel gas or another combustible, gaseous substance is also introduced via the channels which can be changed in cross section.
  • the cross-section-changing element will be a lance that can be adjusted within the mixing zone, as is also proposed according to the prior art.
  • the lance tip can have one or more openings for the supply of fuel and / or air, it also being possible to control the conditions in the combustion chamber.
  • FR-B-2184 340 a burner arrangement for acid gases (rich in H 2 S) is known.
  • a gas supply line which can be closed with a curved, axially adjustable stopper part, opens centrally and at the end into a mixing and combustion chamber.
  • An open ring channel is arranged as an air supply opening peripherally to the mouth of the gas supply line. The air supply cannot be adjusted at the same time with the adjustment device for the plug of the gas line. The gas flowing around the sides of the plug part is caught by the air flow and taken away. Accordingly, the device according to FR-B-2184340 has no common control element and also no hollow strands for the gas supply, which open directly into the air flow.
  • FIG. 1 shows a cross section through a burner arrangement of the type that can be used, for example, when burning natural gas in a boiler in the order of 12000 kJ / h.
  • Natural gas or related gases or gas mixtures such as methass, town gas and the like, are primarily suitable as fuel. However, it is possible to introduce a fine carbon-air mixture or an oil-air aerosol.
  • the burner arrangement adjoins a boiler wall 2.
  • the burner arrangement 1 has a housing 3 which is essentially cylindrical in shape and comprises a plurality of parts arranged concentrically to one another. From the outside inward, the housing 3 initially surrounds a cylindrical air duct 4, to which combustion air is fed via a line 5 at a pressure above atmospheric pressure, for example 110-130 kPa can.
  • a cylindrical connecting piece 6 Concentrically within the air duct 4 is a cylindrical connecting piece 6, which is fitted and held with an end face 7 in a burner holding collar 8.
  • the nozzle part 6 is drilled out along its entire length.
  • the nozzle part 6 comprises a fuel-air mixing chamber 11, the volume of which can be changed by a lance 12 movable back and forth within the nozzle part 6.
  • the front part 13 of the lance 12 serves as a control member, as will be explained.
  • the lance 12 can be moved back and forth manually, for example, with the aid of a lever 14, with a pneumatic device or with similar devices as are known per se.
  • Numerous channels 15 open into the mixing chamber 11 from the side, which preferably have the shape of slots and which differ in their direction from the normal direction, i. H. contain a tangent to an imaginary circle within the mixing chamber 11 in its preferred direction. These channels 15 are therefore at the same time swirl-generating devices which generate a vortex flow with the aid of the air flowing through the air channel 4 within the mixing chamber and in the downstream combustion zone within the boiler space 10.
  • the channels 15 can be more or less closed with the aid of the lance 12, and the air supply can be metered.
  • the gas supply takes place via a feed line 17, which ends in a cylindrical distribution channel 18 and continues into a plurality of strands 19 which run within the connecting piece part 6 parallel to the axis of the lance 12.
  • ignition means not shown
  • the gas-air mixture burns within the casing tube 9 and in the boiler space 10.
  • a stable flame is generated in that the flow is relatively strongly swirled.
  • the front part 13 acts as a cross-sectional changing member for the entirety of the channels 15, so that the supply of the gas-air mixture can be controlled. As a result, the performance of the burner arrangement can be varied in a very simple manner.
  • FIG. 2 shows the fuel-air mixing chamber 11 in a somewhat more detailed representation with further details.
  • numerous slot-like channels 15, here for example twenty, are let into the nozzle part 6, through which the air can flow. Due to the corresponding tangential position of the slot-like channels 15, the air gets into a vortex shape.
  • a gas supply line 19 opens within a channel 15, the gas being carried along by the air.
  • the front part of the lance 12 carries a further feed channel 20 which ends in an opening 21. Through this channel 20, which is guided within the lance 16, liquid fuels can also be introduced, for example.
  • Figure 3 shows an embodiment in which a part of the gas line strands, here designated 23, opens into openings 24 which end on the outer end face 25 of the mixing chamber 11.
